Why Bilstein B4 OE Replacement (Air) for This Application?
This B4 OE Replacement Air component is intended to restore the vehicle's original air-suspension function with an application-matched Bilstein replacement rather than converting the chassis to a conventional spring/damper layout. For the Audi / Volkswagen application shown here, Bilstein assigns this product to Front Left, Rear Left, Rear Right, Front Right, so the part should be chosen by both chassis fitment and suspension position.
